Some of these policies can be easily implemented and enforced by a strong, committed government, not fearful of opposition, and willing to seek and build consensus over possibly unpopular policies. Others require a great behavioural change, and are therefore likely to bear their fruit only in the long-term.
Hi,
Would this idiom be appropriate in a formal context? Also, If I can retain it, should it be 'bear fruit' without 'their'?
Thanks in advance!
(PS: are there any mistakes in the sentence?)
